Why Timing Matters: At What Age Should You Get a Colonoscopy?
When it comes to your health, timing is everything—especially when it comes to preventive screenings like colonoscopies. Colorectal cancer is one of the most common and preventable cancers, yet many people delay getting screened. Understanding the right age to schedule your first colonoscopy and factors that may require earlier testing can make all the difference in detecting issues early and improving long-term outcomes.
In this article, we’ll explore the recommended age for a colonoscopy, the risk factors that may influence your screening schedule, and why staying proactive with your health can save lives.
What is a colonoscopy?
A colonoscopy is a medical procedure used to examine the inside of the colon (large intestine) and rectum for abnormalities such as polyps, inflammation, or signs of colorectal cancer.
During the procedure, a colorectal surgeon or gastroenterologist inserts a thin, flexible tube with a small camera (colonoscope) into the rectum, allowing for a detailed view of the colon’s lining. This enables doctors to detect, biopsy, or remove growths – hopefully before they develop into cancer, making colonoscopy a vital tool for early detection and prevention.
The procedure typically takes about 20 minutes and is performed under sedation to ensure patient comfort.
Why get a colonoscopy?
Getting a colonoscopy is one of the most effective ways to detect colorectal cancer and detect digestive health issues early. Many cases of colorectal cancer develop from polyps—abnormal growths in the colon—that can be removed during a colonoscopy before they turn into an invasive cancer. Early detection is key, as colorectal cancer often has no symptoms in its early stages.
By undergoing routine screenings, you significantly reduce your risk of developing serious complications and improve the chances of successful treatment if any issues are found.
Beyond cancer prevention, a colonoscopy can also help diagnose conditions such as inflammatory bowel disease (IBD), chronic diarrhea, or unexplained abdominal pain, giving you and your doctor the information needed to maintain your digestive health.
Current Recommendations: When to Start Colon Cancer Screening
Health experts have updated colon cancer screening guidelines to ensure early detection and prevention of colorectal cancer. The American Cancer Society (ACS) now recommends that adults at average risk begin regular colon cancer screening at age 45, lowered from the previous recommendation of 50. This change is due to the rising incidence of colorectal cancer in younger adults.
Screening options include stool-based tests and visual exams like colonoscopy or CT colonography (virtual colonoscopy). The choice of screening method depends on individual health, risk factors, and availability.
For individuals with a higher risk, such as those with a family history of colorectal cancer, inflammatory bowel disease (IBD), or certain genetic conditions, screening may need to start even earlier. It’s important to discuss personal risk factors with your doctor to determine the right time for screening.
Age For First Colonoscopy: When Should You Start?
The recommended age for your first colonoscopy depends on your risk level for colorectal cancer. For average-risk adults, the American Cancer Society (ACS) advises beginning screening at age 45.
For screening, people are considered to be at average risk if they do not have (Please discuss your risk with your physician):
- A personal history of colorectal cancer or certain types of polyps
- A family history of colorectal cancer
- A personal history of inflammatory bowel disease (ulcerative colitis or Crohn’s disease)
- A confirmed or suspected hereditary colorectal cancer syndrome, such as familial adenomatous polyposis (FAP) or Lynch syndrome (hereditary non-polyposis colon cancer or HNPCC)
- A personal history of getting radiation to the abdomen (belly) or pelvic area to treat a prior cancer
A colonoscopy is considered the gold standard because it not only detects cancer but also allows doctors to remove polyps. Most people can wait 10 years before their next colonoscopy if no abnormalities are found. However, those with abnormal findings may require more frequent follow-ups.
If you have a higher risk of colorectal cancer, you may need to start screening earlier than 45. Individuals with a family history of colorectal cancer or polyps, a personal history of inflammatory bowel disease (IBD), or certain genetic conditions like Lynch syndrome should talk to their doctor about an earlier screening plan.
In some cases, screenings may begin as early as 40 or even younger, depending on specific risk factors. Consulting a healthcare provider is the best way to determine the proper screening timeline for your individual health needs.
Colonoscopy Age Guidelines for Women
Colorectal cancer is a leading cause of cancer-related deaths in both men and women, and the recommended age to begin screening is the same for both genders. The American Cancer Society (ACS) recommends that women at average risk begin regular colonoscopy screenings at age 45.
For women with a family history of colorectal cancer, inflammatory bowel disease (IBD), or genetic conditions like Lynch syndrome, screenings may need to start earlier. Women in these higher-risk groups should speak with their doctor to determine the appropriate age to begin screening, which could be as early as age 40 or younger, depending on their individual risk factors.
Women should also be mindful of other factors, such as lifestyle choices and personal medical history, which may influence the need for more frequent screenings. Regular screenings are a crucial part of maintaining digestive health and reducing the risk of colorectal cancer.
Risk Factors Influencing Screening Age
Certain risk factors can significantly influence the age at which you should begin screening for colorectal cancer. Understanding how these factors affect your risk can help you and your doctor determine the appropriate age and frequency for your screenings, ensuring early detection and prevention of potential issues.
Risk Factor to Consider: Family History of Colorectal Cancer
A family history of colorectal cancer is one of the most significant risk factors when determining when to begin screening. If you have a first-degree relative (parent, sibling, or child) who was diagnosed with colorectal cancer, especially at an early age, your risk of developing the disease is higher than someone without this family history.
In these cases, the American Cancer Society recommends starting screenings 10 years earlier than the age at which your relative was diagnosed or by age 40, whichever comes first. For example, if your parent was diagnosed at age 45, you should begin screenings at age 35.
Having multiple family members with colorectal cancer or a history of colorectal polyps can further increase your risk, which is why it’s important to discuss your family’s medical history with your healthcare provider. If you have a genetic condition like Lynch syndrome or familial adenomatous polyposis (FAP), which both increase the likelihood of developing colorectal cancer, your doctor may recommend even earlier or more frequent screenings.
Signs You Need a Colonoscopy
While regular screenings are essential for everyone starting at the recommended age, certain signs and symptoms may indicate the need for a colonoscopy even before you reach the typical screening age.
If you experience persistent abdominal pain, bloody stool, or unexplained weight loss, these could be warning signs of colorectal cancer or other gastrointestinal issues that require immediate attention. Changes in bowel habits, such as chronic diarrhea, constipation, or feeling like your bowel doesn’t empty completely, should also not be ignored.
These symptoms may not always indicate cancer, but they can signal other conditions, such as inflammatory bowel disease (IBD) or colorectal polyps, that may require a colonoscopy for diagnosis.

What to Expect During a Colonoscopy
Understanding what to expect during a colonoscopy can help alleviate any concerns and make the experience more comfortable.
Before the procedure, you’ll be asked to follow a bowel prep regimen, which involves drinking a special solution to cleanse your colon. It’s important to follow these instructions carefully to ensure your colon is thoroughly cleaned out, as this will allow the doctor to see any potential issues clearly during the procedure.
On the day of the colonoscopy, you’ll be given a sedative or anesthesia to help you relax and minimize discomfort. The procedure itself usually takes between 30 and 60 minutes. During the colonoscopy, the doctor will gently insert a long, flexible tube (colonoscope) through the rectum and into the colon.
The colonoscope is equipped with a small camera, which allows the doctor to view the lining of the colon and rectum. If any abnormalities, such as polyps, are found, they can often be removed during the procedure. After the colonoscopy, you’ll spend time in a recovery area as the sedative wears off.
Most people can go home the same day, but it’s important to arrange for someone to drive you, as you’ll be groggy from the sedation. While there may be some mild bloating or cramping afterward, any discomfort usually resolves quickly. Your doctor will discuss the results with you and recommend any follow-up care if needed.
Frequently Asked Questions About Colonoscopies
At what age should I start having colonoscopies?
For individuals at average risk, the American Cancer Society recommends starting colonoscopy screenings at age 45. However, if you have a family history of colorectal cancer or other risk factors, you may need to start screenings earlier. Be sure to consult your healthcare provider to determine the appropriate age based on your personal risk.
How often should I have a colonoscopy?
If your first colonoscopy is clear and no abnormalities are found, you typically need another one every 10 years. However, if polyps or other issues are discovered, you may need to undergo more frequent screenings, such as every 3 to 5 years, depending on the size and type of polyps found. Your doctor will provide personalized recommendations based on your results.
What are the risk factors that may require earlier colonoscopy screenings?
Certain factors increase your risk of developing colorectal cancer, making it important to start screenings earlier. These include:
- A family history of colorectal cancer or polyps
- Inflammatory bowel disease (IBD), such as Crohn’s disease or ulcerative colitis
- Genetic conditions like Lynch syndrome or familial adenomatous polyposis (FAP)
- Personal history of polyps or previous colorectal cancer
- Lifestyle factors like smoking or a high-fat, low-fiber diet
Is the colonoscopy procedure painful?
Most people experience minimal discomfort during a colonoscopy due to the sedatives and anesthesia given beforehand. You will be relaxed and comfortable during the procedure, and any discomfort afterward, such as bloating or mild cramping, is typically short-lived. After the procedure, you may feel groggy, so it’s important to arrange for someone to drive you home.
What should I expect during the preparation for a colonoscopy?
Proper preparation is essential for an effective colonoscopy. Your doctor will provide detailed instructions, which usually include following a clear liquid diet for a day before the procedure and taking a bowel-cleansing solution to empty your colon.
Following these instructions carefully is crucial for ensuring a successful colonoscopy, as any remaining stool can interfere with the doctor’s ability to view the colon lining clearly.
What if I have symptoms before reaching the recommended screening age?
If you experience symptoms such as persistent abdominal pain, changes in bowel habits, rectal bleeding, or unexplained weight loss, you should consult your healthcare provider, even if you’re not yet at the recommended screening age.
These symptoms may indicate an underlying condition that requires further evaluation, such as colorectal cancer, inflammatory bowel disease, or other gastrointestinal issues. Your doctor may recommend earlier screening based on your symptoms.
How Often Should You Have a Colonoscopy?
The frequency of colonoscopies depends mainly on your individual risk factors and the results of your previous screenings. For most people at average risk, a colonoscopy is typically recommended every 10 years starting at age 45. This timeline assumes that the previous colonoscopy was clear, meaning no polyps or signs of cancer were found.
If any abnormalities are detected, such as polyps, the doctor may recommend more frequent screenings, usually every 3 to 5 years, depending on the size, number, or type of polyps found. Regular screenings help detect issues early, improving the chances of successful treatment and prevention of colorectal cancer.
